Bug Description
Binary package hint: mono
When an application is being run we expect to be able to see the non-latin characters like CJK ones.
What happens is they're being shown as empty boxes|squares.
My Ubuntu version is Maverick and i'm using the default mono and winforms packages:
- libmono2.0-cil 2.6.7-3ubuntu1
- libmono-
Afaik the problem is related to WinForms or to Ubuntu itself.
Someone addressed this as an issue in thaifonts-scalable package. But as long as i'm not using that package and that issue is fixed for maverick, this is not the same bug. File /etc/fonts/
How to reproduce the issue. Lanch a mono application, like KeePass2 and type in the search box a CJK text or paste one like 我 (for chinese) or 私、わたし (for japanese). They're instantly shown as empty boxes.

I've tried to use this command
> export LANG=ja
> mono KeePass.exe
then i get the following message
Gtk-WARNING **: Locale not supported by C library.
Using the fallback 'C' locale.
cause i know the KeePass.exe support those characters, i was running it on Windows (either real or virtualized) and characters are being shown correctly. I think it is an issue in the mono libraries for Ubuntu.
some people reported there's no such issue in OpenSuSE, maybe cause other linux suse c++ rather than pure c...
is maybe this problem caused by some pure c libraries or the mono libraries in Ubuntu?
